Zusammenfassung: | To provide a powder granule that has superior handleability and safety and can improve the working environment, wherein the powder granule can improve the raw material supply stability and supply precision in the preparation of resin compositions, contributing to improved productivity of resin moldings.SOLUTION: A powder granule includes powdered raw material A, and a binder. The binder includes binder powder B that satisfies all of the following requirements (1)-(3). The content of the binder powder B is 50 pts.wt. or more relative to 100 pts.wt. of the total amount of the binder contained in the powder granule. Requirements (1): the binder powder B can pass through a sieve of 30 mesh; (2) the softening temperature is 50°C-160°C and (3) the weight average molecular weight of 10,000 or more and 150,000 or less.SELECTED DRAWING: Figure 1
